mites! Oh no...

[tcrane]

Hey all, I picked up a Dendrobium lanyaiae from Andy's Orchids recently at the SF Orchids in the Park expo (which was fantastic, btw), but just returned from a week's vacation to a full on infestation on the plant. Looks like mites of some kind, full on life-cycle - adults with black wings, and more translucent ones which look like younger insects. There's a bit of webbing on the stick, and the mites are fully in and around the medium - it's a stick mounted plant. Plant still seems healthy, but I'm freaked out - it was in my tank with my other mounted plants, but looks like nothing has spread so far.

There's a few holes on the stick, and I'm thinking that the mites arrived inside those, as they seem fully infested! Would neem oil work on these jerks, or do I need something stronger? Thank you for any advice!
